FLUID MOTOR.

Application filed October 19, 1925. Serial No. 63,450.-

This invention relates to apparatus for deriving power from fluids in motion, such as air, and is an improvement upon the fluid motor disclosed in my Patent No. 1,471,095, granted October 16, 1923.

An object of the invention is to provide means for regulating the speed of the rotor element automatically, whereby the speed will not vary in accordance with fluctuations in the velocity of the wind or other driving fluid. I

A further object. of the invention is to simplify the construction of the motor and to provide a device which may be readily constructed and will operate with a minimum loss of power.

Other objects of the invention will become apparent as the description proceeds, there being shown in the accompanying drawings certain embodiments of the invention.

In the drawings:

Figure 1 is a top plan view,

Figure 2 is a side elevational view,

Figure 3 is a top plan view of a modified construction, and

Figure 4 is a side elevational view of the device shown in Figure 3.

Referring to the drawings for a more detail description, 10 indicates a support in the form of a tower carrying at its upper end a bracket 11, upon which rotates a frame having track followers 12 positioned above and below the track and carried by brackets 13 which depend from the frame. The frame is substantially circular and comprises a bottom 14 resting directly upon an annular strip 15 to which the brackets 13 are secured. The top 16 of the frame is spaced from the bottom by means of vertical spacing strips 17 and one side is closed by a wall 18 which extends for substantially 180 around the frame and partially encloses a rotor element having substantially tangentially extending vanes 20, the rotor having a bearing 20f and being positioned on a drive shaft 21 which extends downwardly and may be connected to any suitable driven element, such as, for example, the generator 22, supported on a platform 23. a

It will be understood that the entire frame rotates freely on the track 11 about an axis which is. concentric with the axis of the rotor. It automatically adjusts itself by means of a tail vane 25 secured by straps 26 to the frame as the wind strikes the vane 25 and maintains that portion of the rotor which is diametrically opposite the vane, facing the directions froniwhich the wind travels. It will be observed that the tail vane 25 is positioned at one end of the casing or wall 18 and adjacent its opposite end is positioned a deflector 27 carried by a bracket 28, this deflector serving to guide the wind into the rotor which it drives in a clockwise direction, as viewed in Figure 1.

In order to maintain thespeed of the rotor substantially uniform, a valve 29 is supported by means of rollers 30, connected therewith by hanger straps 31, from an arcuate track 32 on the top of the frame. The lower end of the valve is guided in a channel 33. When inoperative, the valve is in the position shown in Figure 1 and registers with the housing wall 18, in which position it is maintained by gravity control means, such as a weight 35, connected with the valve by means of a cable 36 extending upwardly over a sheave 37 and secured at 38 to the valve.

For sliding the valve horizontally over therotor, a vane 39 is mounted upon a vertical rock shaft 40 pivoted in the frame and the vane is connected with the valve by means of a cable 41 traversing pulleys 42, 43 and secured at 44 to the valve. It will be noted that the vane normally extends outwardly from the casing in substantially a radial direction (Fig. 1) and at substantially a right-angle to the path which the wind takes upon entering the rotor. Should the velocity of the wind increase so that the speed of the rotor tends to vary, the vane will be moved to slide the valve outwardly over the rotor and thereby the area of the uncovered portion will be controlled to regulate the speed of the rotor.

Referring to Figures 3 and 4, the device here illustrated is substantially the same as that shown in Figures 1 and 2, with the exception that upon the rotor 20 arev a number of brackets or supports 76 carrying power devices, such as electric motors 77 having propellers 78. The motors may derive power from any suitable source and thereby drive the propellers to cause operation of the impeller or rotor 20 when the wind force subsides or is insufficient to instigate operation of the device. After the impeller com- It will be understood that devices of this character may be readily made up for use as toys.

Numerous modifications may be made in the structure illustrated and described Without departing from the invention as defined by the following claim:

I claim:

In an apparatus of the class described, a support having a horizontally disposed angle iron ring, its horizontal flange forming a circular track and its vertical flange forming a means of attachment, a supporting member, brackets depending from said member, each bracket having a pair of arms of unequal length and having rollers mounted adjacent their free ends and engageable with the top and bottom surfaces of said horizontal flange, and a windmill frame mount ed on said supporting member.

In testimony whereof I have hereunto set 20 my hand.
